Li2NiO3
Li2NiO3 is a thermodynamically stable, semiconducting layered oxide used in the study of lithium-based battery materials.
About Li2NiO3
Li2NiO3 is a semiconducting member of the layered lithium transition-metal oxide family. As a thermodynamically stable phase located on the convex hull, it represents a structurally robust candidate for electrochemical applications where phase integrity is paramount.
This material is of significant interest in the development of advanced energy storage systems. Its structural characteristics and electronic properties make it a subject of ongoing investigation for researchers aiming to optimize cathode performance and stability in lithium-based battery architectures.
Key Properties
Cross-validated computational properties for Li2NiO3, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
